l v 'Be itknown that I,'RUFUs W. CnoUSE, of. Westminster, in the countyof Carroll, and State of Maryland,

have invented anew and useful AImprovement .in Pumps;` and'4 I do hereby declare that the 'following' is a full clear, and exact'description ofthe construction and operation of the same, reference being had to the annexed drawings, making a part of this'specitieatlon, in which- 4Figure l is a cross-section through the line x, :cof fig. 2. v

Figure 2 is a longitudinalcross=section through `the line y y of fig. 3.

4Figure 3 is a side elevation, the near wall of thevalvcc'hamber being'removed.

l Thisinvention relates to the `class-of4 double-acting-cylinder pumps,I andconsists. in'avnew and improved arrangementof thelvalves, by 'whichlpower is economized, while the machine is rendered less complicated and less liable to get o'ut of order.

In the drawings,A represents theeylindcr; B, the plunger or piston; B, the piston-rod; I, theindu'ction, and E the cduction-pipes ofmypumpj.

In n. chamber alongside of the cylinder correspondingl tothe steamfchcst of al steam-engine, four apartments, C Gl C? C3, are arranged` in nl straight line, the two end ones communicatingfdircctly with the eductonpipe through theopeu ports e e', the two centreones 4communicating with thc induction-,pipe-throu'ghfthevalve- 'ports t' z", each-centre'apartment communicating directly with the end of the cylinder nearest to it through thel open passage F, which` is tapped underV thecentrerof` the end apartment below which it runs, and at that point communicates with such @depart-meut through a value-port, d d. I I

y All the water, therefore, that passes from the induction-pipe tothe right-hand end of the cylinder, must pass through the righthand centre apartment C2, and all that passes to the other end of the cylinder must pass through the left-hand centre apartment C1, while all theI water that passes'from the right-hand end oi the cylinder to the` eduction-pipe must pass thrbugh the right-hand end apartment C3, and all that passes to the educltioh from the other end of .the cylindermust pass through the-left-hand end apartment C.

Having`- thus premised, I will proceed to describe particularly the operation of this improved pump, rst remarking that all four of the valves, d fZvvz' ji", seat downward, and that I prefer ball-valves to any other for this purpose. l l l To understand'the operation of this pump, letv us suppose the plunger B in the position shown in dotted lines in fig. 2, and movingto the'lei't. In this case tllesuction through the passage Ff will seat valve-0', and close the way' to theY eduction,while the-same suction will raise valve cf and open the way to the induction, and

the right-hand end'of the cylinder will iill with water.I The plunger, approaching the left-handen-d ofthe cylinder, will force the water out of that end through the passa-ge F, intov the apartment Ci, where, inlattempting to escape into the induction-pipe, it will close the valve c', and cut of?I its own' escape in' that direction. The current will't'hen flow through 'the passage F,lit`t the valve c,- and pass through apartment C to the cduction# pipe, where it will escape. i Y

When the vmotion of thc plunger is reversed, the action ofthe parts, as here described, will be reversed also.

This pump is simple in construction and operation, compact, yand Iall its parts may becast strong and durablc,`so "that it will lastffor many years without getting out of order.I It throws the water rapidly by direct action, and utilizes all the power employed to tllefullest extent." y

A pump of suiiicient capacity for ordinary purposes can Vin this way heV made to occupy but a few cubic inches, Aand the eduction-pipe may he made of any ordinary-pipe or hose, taking up butin. uiere triiie o'f space.

'Having Athus described my invention, what I claim as new, and desire t secure'by LettersPatent, i's--A-V rIhe combination and 'arrangement of the cylinder'A, plunger D, inductionvI,and'educton E, when conf.

nected by the apartments C C1 C2i-()3 and the passages F FV', provided with the valves c crc cf, all, the said parts being constructed, arranged, and operating together, substantially in the manner and. for the purposes set forth. l

To the above specification of my'iniprovement I havel'signed my hand,` this 31st day of January, 1868. "RUFUs W.,oRoUsE. w
